optimize batches containing multiple updates to the same rows
-------------------------------------------------------------
Key: CASSANDRA-2583
URL: https://issues.apache.org/jira/browse/CASSANDRA-2583
Project: Cassandra
Issue Type: Improvement
Components: API
Affects Versions: 0.8 beta 1
Reporter: Jonathan Ellis
Assignee: Pavel Yaskevich
Priority: Minor
Fix For: 0.8.1
Currently we turn batches into one RowMutation per statement. This is
suboptimal if we have multiple statements operating on the same row. This could
happen either with generated code, or deliberately to allow different options
to different columns in the row, e.g. for TTLs (CASSANDRA-2476).
